+  <title>PDFKit, ImageKits: Buffer overflow</title>
+  <synopsis>
+    PDFKit and ImageKits are vulnerable to an integer overflow and a stack

+    <p>
+    Maurycy Prodeus discovered an integer overflow vulnerability possibly
+    leading to a stack-based buffer overflow in the XPDF code which PDFKit
+    is based on. ImageKits also contains a copy of PDFKit.

+  </description>
+  <impact type="normal">
+    <p>
+    By enticing a user to view a specially crafted PDF file with a viewer
+    based on ImageKits or PDFKit such as Gentoo's ViewPDF, a remote
+    attacker could cause an overflow, potentially resulting in the
+    execution of arbitrary code with the privileges of the user running the
+    application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    PDFKit and ImageKits are not maintained upstream, so the packages were
+    masked in Portage. We recommend that users unmerge PDFKit and
+    ImageKits:
+    </p>
+    <code>
+    # emerge --unmerge gnustep-libs/pdfkit
+    # emerge --unmerge gnustep-libs/imagekits</code>
+    <p>
+    As an alternative, users should upgrade their systems to use PopplerKit
+    instead of PDFKit and Vindaloo instead of ViewPDF.
+    </p>
